. forming a partof this speccation, in which- Fi ure l shows a sideA elevation; Fig. 2, a.

gan, November 21, 1876. Y

Our improvements consist of devices for lev-l elingthe. platform supporting the apparatus to accommodate'itv to the inequalities of the ground, devices' by which the pipe or tube is elevated after its sections have been coupled togethendevices by which said pipe or tube is revolved upon its axis, a device for stiffening and strengthening lthe same, an improved adjustable nozzle, devices for operating the same, devices for supporting the same in its differentpositions, and an improved arrangement of valve or cutoff.

Our invention will -be best understood by reference to the accompanying drawings, in which a shows the wheels ofthe truck orcarriage,

supporting. upon springs b a heavy frame, c.`

upward through the frame and operating tov elevate or depress the side of the platform, `making it oscillate iipo'n its longitudinal axis.

" When leveled by means of this screw, it is re'- Within this sleeve is the lower section, a', of

the stand-pipe N, so arranged as to revolve easily, its lower end entering a stufling-box` in the before-mentioned T-piece, or in the lower end of `the sleeve. The section, Fig. 6, shows the general arrangement of these parts, though, of course, we do not limit ourselves to any precise form of stuffing-box or` means of packing the connection.

The T-piece, to which the hose from the en, gines or hydrants are attached, always remains stationary and unaffected by the revolution of the pipe N, which revolution is communicated to it lthrough a` gear, o, fastened thereto, by means of a worrn,p, upon a shal't, p, journaled upon supports or arms secured to the sleeve, enabling the stream to be directedtoward any point of the horizon. j

5 Goncentric with the trunnion lc, and bolted to the sleeve l, is a segmental gear,4 q, operated bya worm, gf, upon a shaft, g3, which sha-ft carries a gear, q, meshing into a pinion upon a shaft, g2, extending to the rear of the machine, at which point it is provided with a hand-Wheel, the revolution of which elevates and retains the pipe in'a vertical or inclined position, as preferred.

Our device for bracing` the pipe consists of a rope, t, preferably of wire, attached at its lower end to the pipe N,`near the point where it enters the' sleeve l, and extendingnearly to the end of the pipe.

Upon the lower section of the pipe n isl an arm, r, pivoted to said pipe, so as to be out of. the way when "not in use. A corresponding arm, r', is attached in like manner'to the upper section, n, After the'pipe has been coupled together the rope t is attached at each end of the pipe and the armsrfr forced out against y roo zle, and, being attached at both ends tothe pipe, turns with it, always -rnaintainingits pol55 lng, and when the modification ofthe former,

stion relative to the streamv and bracing the` Y upon a drum provided with appropriate ratchet devices andv locatednear the platform of the in Fig. 4, and it is necessary pipe against its reaction.

Our ilnprovementvin the adjustable nozzle we yconsider-of great importance. `It consists in making a section ofthe pipe of iiexible material, so that as the elevation ofthe stream is varied the water may be conducted through* a the minits flow'.A This section is preferably placed upon the extremity ofthe pipe, although it may be attached to auelbow `at any,intermediate point between ba'se'and top. In practice it is about eighteen inches in length,and may be sliffened and strengthened by a spiral spring, like the ordinary suctionhose. I tis tipped with the usualnozzle 1/.- The force'of the water is sufficient to elevate it to a perpendicular position, or, if desired, springs may be attached for the'purpose. If this `is'done, the vmanner vin which they should mum of resistance to i section is drawn down and in avertical plane, se as to control the elevation of. the stream, by a cord, e, att-ached yto the nozzle, and lhaving its lower end wound made adjustable machine.

the stream may be placed in the pipe near he point where it enters the 'sleeve l, the lever 3 operating itbeing thus withine'asy reach from the platform, like revolution to the pipe. l v

Inorderto prevent any breakin the flexible portion vof' thepipew-when the same isidepressed, we provide lmeans'v by whicha true down, thus preventing anyimpedinientt0 the stream. This may be effected in several which is shownin Fig. l. This. consists cfa metallic former, 5, att'ache'd to cave onvits inn\;r surface, in cross-section, to receive the section a'. At the upper end ofsaid section is a second former, 6, reversed in'posito support. the; section when itisdrawn down intoa curved position. A modication of this is shown in Fig. 4., in

6, is shown as bent into an are of a circle, or-nearly so. With this A metallic casing or frame, 7, is attached to the back ofthe'section w, toguard against bulg- Fig.4, is usedfthis casing-may be extended, as shown in dctted lines at 8, and'provided with slots 9, serving as guides forthe former as itmoves downward with the section a.

The valve or cut-olf of the stream may be placed at the extremity of the nozzle, as'shown to provide means for operating the valve from the .platform of the apparatus.- The method of doingithis is shown in Fig. 4.

it first passes loosely over the v upon and opening'the "'stopcockthrough its lever -l2. When, however, the stop or check 16 comes in contact with the; pulley-casing at yle, the further winding of the cord acts upon the iiexiblesection, as before described,draw-v ing it downward. The valve or stop-cock is closed by means of a spring.

AWe do. not limit ourselves to the particular pulleys above described, as it may be varied. A y

It will,l be observed that although the details ofthe invention patented to Logan, as-before mentioned, have been varied, the funda-mental principles have been preserved, both the tube or pi pemovable about 'a vertical axis and de pulleys, actin g liveriugthe water at an elevation, and the -nozzle or nozzles adjustable in a vertical plaine,

entering intoand forming a part of the apparatus herein described.
